The former Indiana state trooper is accused of killing his family in the garage of their Georgetown, Ind., home 13 years ago.

He's being tried in Lebanon due to publicity.

"He's cautiously hopeful. He's just hoping that this time things will unfold in the way they should," said Camm's sister, Julie Blankenbaker.

Jurors heard more from the lead technician at the crime scene, Sgt. Jim Niemeyer, as the defense continued its cross-examination of him with the intention of proving the investigation was sloppy and mistake-filled in a rush to judgment.

Niemeyer admitted on the stand that after standing at the edge of the garage for five minutes, before he even saw all of the victims or collected a single piece of evidence, he thought, "This is a David Camm" crime.

Niemeyer was one of the people who processed the evidence nearly 13 years ago.

Camm's wife, Kim, and their kids, Brad and Jill, were shot to death Sept. 28, 2000, in the garage.

Defense attorney Stacy Uliana hammered Niemeyer, pointing out he only fingerprinted the family's Ford Bronco, but not inside the home.

The defense contended the murders were a burglary gone wrong, committed by a man already convicted, Charles Boney.

Niemeyer testified he lifted a fresh palm print from the outside of the car, later identified as Boney's.

Uliana also pointed out Niemeyer overlooked a sweatshirt found in the garage and didn't properly collect it for evidence.

That sweatshirt ended up in Brad Camm's body bag, where she said contamination may have occurred.

It also had Boney's DNA on it.

The state called its third witness before noon on Friday, an ISP investigator called to document the scene, including the interior of the house.

The prosecution contended nothing was disturbed because it wasn't a burglary but an act committed by Camm.

During the afternoon, the prosecution called Brandon Beavin to testify.

He was the Camm's neighbor in September 2000 and recalled seeing a black Cadillac with Kentucky plates speeding toward the home several hours before the murders happened.

He said it peeled out even faster.

Beavin later identified a picture of Boney’s car as similar.

"I think it’s going relatively smoothly. I was hoping to get a few more witnesses in, but basically most of the witnesses I thought I’d call by now testified," special prosecutor Stan Levco said.

Camm's first trial was held in Floyd County in 2002.

The appeals court tossed his conviction in 2004 due to unfair testimony that prejudiced the jury.

Camm was retried in Warrick County in 2006 and again found guilty.

That verdict was set aside in 2009, again because of improper evidence being admitted.
